| MuMaBus Release status: experimental [box doku] | |
|---|---|
| Description | Bus to connect different devices in the lab and in the outside world |
| Author(s) | tiefpunkt |
The MuMaBus is a framework to connect different devices in the lab to each other and with outside services. This is currently done using MQTT.
Bus details
- MQTT Broker:
mqtt.munichmakerlab.de- Note: Old nodes in the bus still use mqtt.tiefpunkt.com. Both brokers are bridged, so messages sent to one broker will be received by devices connected to the other as well. But new devices should always use mqtt.munichmakerlab.de
- Port: 1883 (unencrypted), 8883 (SSL, using a CACert certificate)
- Anonymous read access to
mumalab/# - For write access, contact Matthias or Severin
